| ITEM | DESCRIPTION |
|---|---|
| 1 | Brake booster connector/check valve |
| 2 | Brake booster |
| 3 | Intake manifold rear cover |

| 5 | Vacuum pump |
Plastic pipes connect the brake booster to the intake manifold and the vacuum pump to provide the vacuum for the brake booster. The connection with the brake booster contains a check valve to maintain the vacuum in the brake booster. An in-line check valve near the connection with the intake manifold prevents air being drawn from the intake manifold and fuel vapor from entering the pipes.
